字典distinguish 有2种搭配：distinguish ... from /distinguish (between)...and...但是看了OG解释后我发现ETS 只承认 distinguish between ...and ...

OG 说：The best choice is C because it uses the idiomatically correct expression distinguishes between x and y  

The other choices use distinguishes in unidiomatic constructions.

我这种感觉对吗？？

sorry 啊！

以前不知道怎么搜索到问题！才重复问问题的！SORRY

研究完以前人的帖子不明白再问！谢谢！

HOHO ！我可以发帖子了！555555！

前几天一直发不了！电脑里有毒和抽风一样！我才麻烦ＧＲＡＣＥ帮我问问题的！我换用了一个浏览器才可以的！

祈祷以后不会再出问题了！55555！可恨的病毒！

这个不是语法的考点，完全是句子意思的理解. mm仔细读几遍就理解了.

distinguish的确有两种搭配，但是意思不一样。distinguish A from B, 意思是把A从B里面分辨出来。distinguish between A and B, 意思是把A和B之间的差异分辨出来.

互帮互助一直是CD的传统，楼上两位做的不错, hehe.
